Abstract
Photometric measurements of stars in the intermediate-age galactic cluster NGC 6633 are presented. From these data the color excess is found to vary slightly across the cluster with an average of Eb – y = 0m.124. The distance modulus is found to be 7m.711 and the turnoff occurs at about (b – y)0 = 0m.l. The cluster is slightly metal poor.
